| 摘 要： | 研究了低成本宽范围双馈感应电机调速风力机，根据数学模型导出矢量控制系统，讨论了三种四象限功率变换器，该风力机在低风速时桨距角不变，保持最佳叶尖速比以获得最大风能；在高风速时储存或释放部分能量，桨距角仅完成限制最大输出功率，减少机械应力，风能储存在风力机机械惯性中，减少力矩冲击。 |
| 关 键 词： | 双馈感应发电机 调速风力机 矢量控制 功率变换器 桨距角 |

| Abstract: | A viable alternative to adjust speed over a wide range at minimal cost using a doubly fed induction generator for wind turbines was introduced. The vector control system by DFIG mathematic models was analyzed. Three kinds four-quadrant power converters were discussed. During a low speed, the pitch angle is a constant, wind turbines keep on the optimum speed ratio between the pitch and wind so as to absorb the maximum energy. During a high speed, wind turbines absorb or release partial energy, and the mechanical stress were less. |
| Keywords: | doubly fed induction generator vector control adjust speed wind turbine |
